One of the biggest questions that's popped up in the minds of most fans during this season of The Flash is" "who exactly is Zoom?" The comics reveal that the speedster is a man named Hunter Zolomon, but questions as to whether or not this would be the actual identity of the villain in the TV show still remained. Well, this week's episode has put those questions to rest, as the face behind Zoom's mask was finally revealed.

This week, the team focused their energies on locating and catching King Shark, who escaped from the custody of ARGUS. Of course, this news was delivered by none other than the Diggles themselves. This hunt for the meta took a bit of time, and it actually involved the West's losing the roof of their house when King Shark came looking for the Flash.

There was also a focus on Caitlyn becoming more distant and cold after seeing Jay "killed" right after she was finally starting to get over the death of her husband and fall in love again. Of course, Cisco was worried about her becoming Killer Frost in this earth as well, and the deliberate choices of Cisco and Barry to tell the others about their dopplegangers was also given a lot of emphasis in this episode.

In the end, however, The Flash saved the day yet again by running on water and creating an electric whirlpool to incapacitate King Shark. Likewise, he and the team decided not to give up on Earth-2, despite the fact that they don't yet know how to reopen the breaches or how to defeat Zoom once they do. The final scene of the episode then showed Zoom carrying Jay Garrick into his lair before removing his mask and revealing the same face as the man he was carrying, thus definitively proving that he's the Hunter Zolomon that Jay pointed out to Caitlyn earlier this season.

This didn't come as much of a surprise, though, as The Flash has been very consistent about keeping the identities of the main characters and villains close to what they are in the comics. If the show was going to continue to follow this pattern of staying faithful to the source material, the only other alternative would have been for a different Hunter Zolomon with a different appearance to have existed in another universe.

In reality, though, this revelation only serves to deepen the audience's interest in the man in the iron mask from Zoom's lair. Who is he? Is he Ronnie Raymond? Is he Eddie Thawne? Is he the real Jay Garrick? Was the man who claimed to be Jay Garrick really an Earth-2 version of Hunter Zolomon who for some reason befriended the team? These are the big questions now, and fans will have to wait just a little bit longer to find out for sure.

Ultimately, this episode of The Flash was up to par with what the show's been delivering on throughout this second season. However, the action sequences in this week's episode were some of the best that have been shown all year, with The Flash and King Shark's final showdown being one of those stand out moments of not only this episode, but of the entire season as well. Likewise, it was great to see both Barry and Caitlyn start to recuperate from their funk at the end - the show's pattern of fixing the internal conflicts of the characters after a brief emphasis on them is really working with the dynamic of the show, unlike Arrow's system (i.e. internal conflict piling on top of internal conflict, each of which are drug out for multiple episodes and even entire seasons). Just as well, Keiynan Loinsdale seems to have found the melody that the rest of the cast is playing to, and he'll likely become just as a beloved part of the show as Barry, Cisco, or Caitlyn as things continue to progress.
